Remove Label - Add New Label - Edit Label in Blogger / Blogspot

how you can edit, add or delete labels in Blogger.
Log in to Blogger, in the Posting section, click on Edit Posts.

See the highlighted regions in the image above.
As soon as you click on Edit posts, you will see all posts written by you (select posts per page as 300 in the right corner of the page).

1. Now to delete any label, click on "Select All". Then in the drop down menu "Labels action", under "Remove label" option you will see the list of all labels, click on the one, you want to remove for ever.

2. To add a label, select all the posts, you want to add the label. Then in the drop down menu "Labels action", under "Apply label" option click on New label.... Finally enter the name of the new label.

3. And in case you want to edit a label, unfortunately there's no direct option given by Blogger.
So do this, firstly in the list of labels column, present at the left side of the page, click on the label you want to edit. Now only those posts are displayed which have this label. Now add a temporary label to these posts. Then delete the label, you want to edit. Now click on the temporary label in the labels list. Now add the new label. Then finally delete the temporary label.
